Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Check for invalid/obsolete
 root *after* making MMU pages available Check for a "stale" page fault, i.e. for an invalid and/or
 obsolete root, after making MMU pages available for the shadow MMU. If reclaiming shadow pages zaps an in-
 use root, i.e. marks it invalid, then KVM will attempt to map memory into an invalid root. On its own,
 populating an invalid root is "fine", but because child shadow pages inherit their parent's role, any
 children created during the map/fetch will be created as invalid pages, thus violating KVM's invariant
 that invalid pages are never on the list of active MMU pages. Note, the underlying flaw has existed since
 KVM first started tracking invalid roots in 2008 (commit 2e53d63acba7, "KVM: MMU: ignore zapped root
 pagetables"), but the true badness only came along in 2020 (Linux 5.9) with the invariant that invalid
 shadow pages can't be on the list of active pages. Note #2, inheriting role.invalid when creating child
 shadow pages is also far from ideal; that flaw will be addressed separately. (CVE-2026-64561)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.56 or later.
